A Comprehensive Summary of Available Legislation and Practices in Demolition and Construction & Demolition Waste Management in the Arctic Region
Novakova, Iveta; Drozdyuk, Tatiana; Ohenoja, Katja; Ayzenshtadt, Arcady; Arntsen, Bård; Perumal, Priyadharshini; Dyvesveen, Martin Skjerve (Peer reviewed; Journal article, 2021)The need for better natural resource use is currently increasingly recognised, and high emphasis is given to the circularity of building materials and the reduction of activities with negative environmental impact. ... -

An overview of trends and regional distribution of thermal ice loads on dams in Norway
Petrich, Christian; Arntsen, Bård (Chapter, 2018)Norway has over 3000 dams, over half of which are concrete dams [1]. Static ice loads are considered as part of dam design and during period safety review. They present a significant fraction of the total design load of ... -
Ice load measurements on Rätan concrete dam using different sensor types
Hellgren, Rikard; Petrich, Chris; Arntsen, Bård; Malm, Richard (Peer reviewed; Journal article, 2021)Concrete dams in cold regions are designed to withstand loads from the ice sheet on top of the reservoir.However, the ice load's magnitude and return period are among the most considerable uncertainties in safety assessments ... -
Influence of large-scale asperities on the shear strength of concrete-rock interface of small buttress dams
Sas, Gabriel; Popescu, Cosmin; Bista, Dipen; Seger, Andreas; Arntsen, Bård (Peer reviewed; Journal article, 2021)This paper presents an investigation of the influence of large-scale asperities on the shear strength of four physical models of a pillar (also known as buttress web)from Kalhovd dam in Norway. The objective was to observe ... -
Influence of large-scale asperities on the stability of concrete dams
Ulfberg, Adrian; Jaime, Gonzales-Libreros; Das, Oisik; Sas, Gabriel; Andersson, Erik; Bista, Dipen; Arntsen, Bård; Seger, Andreas (Chapter, 2022)For concrete dams founded on rock, there are only a few options in the common analysis methods to account for large‐scale asperities. However, previous research alludes that they have a significant impact on the behaviour ... -
Low-temperature (-10 °C) curing of Portland cement paste – synergetic effects of 1 chloride-free antifreeze admixture C-S-H seeds, and room-temperature pre-curing
Alzaza, Ahmad; Ohenoja, Katja; Strøm Langås, Isak; Arntsen, Bård; Poikelispää, Minna; Illikainen, Mirja (Peer reviewed; Journal article, 2021)Cold weather drastically shortens the construction season in northern regions. Low ambient temperatures are known to have detrimental impacts on the reactivity and hardened performance of cementitious materials. This study ... -
Numerical analysis of ice loads on Taraldsvikfossen dam
Seger, Andreas; Sand, Bjørnar; Arntsen, Bård; Petrich, Chris; O'Sadnick, Megan (Chapter, 2020)Static ice loads (ice actions) are a key design parameter for dams in cold climates. Since 2012,ice stresses have been measured at Taraldsvikfossen reservoir located in Narvik, Norway. Similar to earlier observations in ... -
Static ice loads on a dam in a small Norwegian reservoir
Petrich, Chris; Sæther, Irina Vasiljeva; O'Sadnick, Megan; Arntsen, Bård (Chapter, 2020)Ice loads on a concrete dam have been calculated from stress measurements in Taraldsvikfossen Reservoir, a small reservoir in Narvik, Norway, during three winter seasons. Ice thickness was in the range of 0.5 to 1.0 m, and ... -
Structural health monitoring of a buttress dam using digital image correlation
Popescu, Cosmin; Sas, Gabriel; Arntsen, Bård (Chapter, 2019)In order to improve the knowledge of the real behaviour of existing structures,structural health monitoring (SHM) is usually carried out. Initial calculations of a buttress dam located in Norway has been carried out to ... -
Time-dependent spatial distribution of thermal stresses in the ice cover of a small reservoir
Petrich, Christian; Sæther, Irina Vasiljeva; Lennart, Fransson; Sand, Bjørnar; Arntsen, Bård (Peer reviewed; Journal article, 2015)Static ice loads (ice actions) are a key design parameter for dams in cold climates. However, their theoretical description is still elusive, introducing uncertainty in design and hindering development of remediation ... -
Winter concreting full-scale field trial of rock tower foundations
Petrich, Christian; Sæther, Irina Vasiljeva; Arntsen, Bård (Lecture, 2018)Winter concreting can be an attractive option for construction in remote areas where concerns about wildlife and soil integrity are prioritized. In order to minimize disturbance of wildlife and to be able to access remote ...
